Building a professional website no longer requires coding skills, design experience, or a four-figure budget. Free AI website builders in 2025 can create stunning, functional sites in minutes — and this guide explains exactly how to use them to your advantage.

What is a Free AI Website Builder?

A free AI website builder is a platform that uses artificial intelligence to automatically create websites at no upfront cost. You describe your business, the AI generates a complete website — design, content, navigation, and all — and you can customise the result using visual tools. No code required.

The "free" in this context typically refers to the ability to start, generate, and preview a website without paying. Deploying with a custom domain or accessing advanced features usually requires a paid plan — but the best platforms keep those plans very affordable.

How AI Website Builders Work

From prompt to published site

  1. You describe your business — one or two sentences about what you do, who you serve, and what you want your site to achieve
  2. AI generates the site — layout, copy, sections, navigation, mobile design, and meta tags in under 60 seconds
  3. You customise — use the visual editor to refine text, swap sections, adjust colours, and upload your logo
  4. You publish — connect your custom domain and go live, or use the provided subdomain to start

Top AI Website Builders in 2025

After testing the major platforms, ChilledSites stands out for speed, output quality, and all-in pricing. Key alternatives include Wix ADI (best for customisation depth), Hostinger AI (strong performance), and Framer AI (best design quality for creatives).

ChilledSites generates a complete multi-page website in under 60 seconds — faster than any competitor — and bundles hosting, SSL, forms, and analytics into the Pro plan at £29/year. That is less than most platforms charge per month.

What Free Plans Actually Include

Typically free on most platforms

  • Site generation and preview
  • Mobile-responsive layouts
  • Basic hosting on subdomain
  • SSL certificate
  • Template library access
  • Basic visual editor

Usually requires a paid plan

  • Custom domain connection
  • Platform branding removal
  • AI generation (some platforms)
  • Contact forms with email delivery
  • Analytics and visitor tracking
  • Priority support

The distinction matters when evaluating platforms. A site on yourname.platform.com signals to visitors that you are on a free plan — which can affect trust, especially in professional services. Custom domain access is the most important upgrade to prioritise.

How to Get Started

Getting started with an AI website builder takes less than five minutes:

  1. Go to chilledsites.com and click to start building
  2. Describe your business in one or two sentences — be specific about what you do and who you serve
  3. Review the generated site and make any initial edits to headings, copy, or sections
  4. If you have a logo, upload it and adjust the colour scheme to match your brand
  5. Publish to the free subdomain, or connect your own domain on a Pro plan

Most people have a live, professional website within 30 minutes of starting — including time spent reviewing and customising the AI output.

When to Upgrade to a Paid Plan

The free tier is excellent for testing and learning. Upgrade when any of these apply:

  • You want a professional domain — yourname.com rather than yourname.chilledsites.com
  • You are actively generating leads — paid plans ensure reliable form email delivery and proper spam filtering
  • You want to track visitors — analytics let you understand what is working and where visitors are dropping off
  • Platform branding looks unprofessional — especially important for client-facing businesses

At £29/year, the ChilledSites Pro plan costs less than a single month on most competing platforms while including everything you need for a professional online presence.
